Catalytic deoxygenation of triglycerides to green diesel over modified CaO-based catalysts

Abstract

Renewable fuel is a promising alternative as a petroleum replacement in view of the current worldwide demand for petroleum fuel, which is catching up with the world's petroleum supply.

Production of green diesel from catalytic deoxygenation of chicken fat oil over a series binary metal oxide-supported MWCNTs

“…Thus, deoxygenation of CFO via removal of oxygenated species (CO 2 , CO) via the deCOx reaction will lead to the formation of C 15 and C 17 hydrocarbon fractions. 45,46 As demonstrated in Fig. 4b, n-C 15 and n-C 17 were obtained as the main hydrocarbon products from catalysed CFO deoxygenation.…”

Efficient deoxygenation of waste cooking oil over Co3O4–La2O3-doped activated carbon for the production of diesel-like fuel

“…Although the atomic radius of oxygen (1.67Å) is larger than that of Co (0.65Å), excess replacement by Co increased the size of the unit cell for CoLaO 3 . 11 The increment in the average crystallite size for the Co 3 O 4(x) -La 2 O 3(y) / AC nano catalyst with an increase in Co dosage is depicted in Table 3. with an increase in Co dosage from 5 to 25 wt%.…”

“…For instance, the use of a bimetallic doped carbon catalyst in the DO of nonedible oil including jatropha oil and WCO was recently explored by our group. 5,6,11 Ni-Ag/AC, CaO-La 2 O 3 /AC, and Ag 2 O 3 -La 2 O 3 /AC nano were found to be effective in removing the oxygenated compound via deCOx pathways and yielded hydrocarbon in the range of 72-89% with product selectively toward n-C 15 + C 17 fractions (82-93%) and could be reused four to six times (Table 5). Notably, Co 3 O 4(20%) -La 2 O 3(20%) /AC nano exhibited excellent catalyst activity with hydrocarbon yield and selectivity of 96% and 93%, respectively.…”

Potential waste from palm empty fruit bunches and eggshells as a heterogeneous catalyst for biodiesel production

“…CaO is one of the potential catalysts for biodiesel production. 15 CaO catalysts can be formed from a calcination process of CaCO 3 . A plentiful waste materialeggshellis a potential material, because it contains more than 94% CaCO 3 .…”
